<p>Test2::Tools::Compare - Tools for comparing deep data structures.</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p><a href="https://metacpan.org/pod/Test::More">Test::More</a> had <code>is_deeply()</code>. This library is the <a href="https://metacpan.org/pod/Test2">Test2</a> version that can be used to compare data structures, but goes a step further in that it provides tools for building a data structure specification against which you can verify your data. There are both &#39;strict&#39; and &#39;relaxed&#39; versions of the tools.</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code>    use Test2::Tools::Compare;

    # Hash for demonstration purposes
    my $some_hash = {a =&gt; 1, b =&gt; 2, c =&gt; 3};

    # Strict checking, everything must match
    is(
        $some_hash,
        {a =&gt; 1, b =&gt; 2, c =&gt; 3},
        &quot;The hash we got matches our expectations&quot;
    );

    # Relaxed Checking, only fields we care about are checked, and we can use a
    # regex to approximate a field.
    like(
        $some_hash,
        {a =&gt; 1, b =&gt; qr/[0-9]+/},
        &quot;&#39;a&#39; is 1, &#39;b&#39; is an integer, we don&#39;t care about &#39;c&#39;.&quot;
    );</code></pre>

<h2 id="ADVANCED">ADVANCED</h2>

<p>Declarative hash, array, and objects builders are available that allow you to generate specifications. These are more verbose than simply providing a hash, but have the advantage that every component you specify has a line number associated. This is helpful for debugging as the failure output will tell you not only which fields was incorrect, but also the line on which you declared the field.</p>

<pre><code>    use Test2::Tools::Compare qw{
        is like isnt unlike
        match mismatch validator
        hash array bag object meta number float rounded within string subset bool
        in_set not_in_set check_set

        T F D DF E DNE FDNE U L
        event fail_events
        exact_ref
    };

    is(
        $some_hash,
        hash {
            field a =&gt; 1;
            field b =&gt; 2;
            field c =&gt; 3;
        },
        &quot;Hash matches spec&quot;
    );</code></pre>

<dt id="$bool-=-is($got,-$expect)"><a id="bool---is-got---expect"></a>$bool = is($got, $expect)</dt>
<dd>

</dd>
<dt id="$bool-=-is($got,-$expect,-$name)"><a id="bool---is-got---expect---name"></a>$bool = is($got, $expect, $name)</dt>
<dd>

</dd>
<dt id="$bool-=-is($got,-$expect,-$name,-@diag)"><a id="bool---is-got---expect---name---diag"></a>$bool = is($got, $expect, $name, @diag)</dt>
<dd>

<p><code>$got</code> is the data structure you want to check. <code>$expect</code> is what you want <code>$got</code> to look like. <code>$name</code> is an optional name for the test. <code>@diag</code> is optional diagnostics messages that will be printed to STDERR in event of failure, they will not be displayed when the comparison is successful. The boolean true/false result of the comparison is returned.</p>

<p>This is the strict checker. The strict checker requires a perfect match between <code>$got</code> and <code>$expect</code>. All hash fields must be specified, all array items must be present, etc. All non-scalar/hash/array/regex references must be identical (same memory address). Scalar, hash and array references will be traversed and compared. Regex references will be compared to see if they have the same pattern.</p>

<pre><code>    is(
        $some_hash,
        {a =&gt; 1, b =&gt; 2, c =&gt; 3},
        &quot;The hash we got matches our expectations&quot;
    );</code></pre>

<p>The only exception to strictness is when it is given an <code>$expect</code> object that was built from a specification, in which case the specification determines the strictness. Strictness only applies to literal values/references that are provided and converted to a specification for you.</p>

<pre><code>    is(
        $some_hash,
        hash {    # Note: the hash function is not exported by default
            field a =&gt; 1;
            field b =&gt; match(qr/[0-9]+/);    # Note: The match function is not exported by default
            # Don&#39;t care about other fields.
        },
        &quot;The hash comparison is not strict&quot;
    );</code></pre>

<p>This works for both deep and shallow structures. For instance you can use this to compare two strings:</p>

<pre><code>    is(&#39;foo&#39;, &#39;foo&#39;, &quot;strings match&quot;);</code></pre>

<p><b>Note</b>: This is not the tool to use if you want to check if two references are the same exact reference, use <code>ref_is()</code> from the <a href="https://metacpan.org/pod/Test2::Tools::Ref">Test2::Tools::Ref</a> plugin instead. <i>Most</i> of the time this will work as well, however there are problems if your reference contains a cycle and refers back to itself at some point. If this happens, an exception will be thrown to break an otherwise infinite recursion.</p>

<p><b>Note</b>: Non-reference values will be compared as strings using <code>eq</code>, so that means &#39;2.0&#39; and &#39;2&#39; will match.</p>

<p>Opposite of <code>is()</code>. Does all the same checks, but passes when there is a mismatch.</p>

<p><code>$got</code> is the data structure you want to check. <code>$expect</code> is what you want <code>$got</code> to look like. <code>$name</code> is an optional name for the test. <code>@diag</code> is optional diagnostics messages that will be printed to STDERR in event of failure, they will not be displayed when the comparison is successful. The boolean true/false result of the comparison is returned.</p>

<p>This is the relaxed checker. This will ignore hash keys or array indexes that you do not actually specify in your <code>$expect</code> structure. In addition regex and sub references will be used as validators. If you provide a regex using <code>qr/.../</code>, the regex itself will be used to validate the corresponding value in the <code>$got</code> structure. The same is true for coderefs, the value is passed in as the first argument (and in <code>$_</code>) and the sub should return a boolean value. In this tool regexes will stringify the thing they are checking.</p>

<pre><code>    like(
        $some_hash,
        {a =&gt; 1, b =&gt; qr/[0-9]+/},
        &quot;&#39;a&#39; is 1, &#39;b&#39; is an integer, we don&#39;t care about other fields&quot;
    );</code></pre>

<p>This works for both deep and shallow structures. For instance you can use this to compare two strings:</p>

<pre><code>    like(&#39;foo bar&#39;, qr/^foo/, &quot;string matches the pattern&quot;);</code></pre>

<dt id="$bool-=-unlike($got,-$expect,-$name,-@diag)"><a id="bool---unlike-got---expect---name---diag"></a>$bool = unlike($got, $expect, $name, @diag)</dt>

<p>Opposite of <code>like()</code>. Does all the same checks, but passes when there is a mismatch.</p>

<p>The <code>is()</code>, <code>isnt()</code>, <code>like()</code>, and <code>unlike()</code> functions can be made to dump <code>$got</code> using <a href="https://metacpan.org/pod/Data::Dumper">Data::Dumper</a> when tests fail by setting the <code>T2_AUTO_DUMP</code> environment variable to &quot;1&quot;. (Alternatively, <code>T2_AUTO_DUMP</code> can be set to the name of a Perl module providing a compatible <code>Dump()</code> method.) The <code>T2_AUTO_DEPARSE</code> environment variable can be used to enable Data::Dumper&#39;s deparsing of coderefs.</p>

<h2 id="QUICK-CHECKS"><a id="QUICK"></a>QUICK CHECKS</h2>

<p><b>Note: None of these are exported by default. You need to request them.</b></p>

<p>Quick checks are a way to quickly generate a common value specification. These can be used in structures passed into <code>is</code> and <code>like</code> through the <code>$expect</code> argument.</p>

<p>Example:</p>

<pre><code>    is($foo, T(), &#39;$foo has a true value&#39;);</code></pre>

<dl>

<dt id="$check-=-T()"><a id="check---T"></a>$check = T()</dt>
<dd>

<p>This verifies that the value in the corresponding <code>$got</code> structure is true, any true value will do.</p>

<pre><code>    is($foo, T(), &#39;$foo has a true value&#39;);

    is(
        { a =&gt; &#39;xxx&#39; },
        { a =&gt; T() },
        &quot;The &#39;a&#39; key is true&quot;
    );</code></pre>

</dd>
<dt id="$check-=-F()"><a id="check---F"></a>$check = F()</dt>
<dd>

<p>This verifies that the value in the corresponding <code>$got</code> structure is false, any false value will do, <b>but the value must exist</b>.</p>

<pre><code>    is($foo, F(), &#39;$foo has a false value&#39;);

    is(
        { a =&gt; 0 },
        { a =&gt; F() },
        &quot;The &#39;a&#39; key is false&quot;
    );</code></pre>

<p>It is important to note that a nonexistent value does not count as false. This check will generate a failing test result:</p>

<pre><code>    is(
        { a =&gt; 1 },
        { a =&gt; 1, b =&gt; F() },
        &quot;The &#39;b&#39; key is false&quot;
    );</code></pre>

<p>This will produce the following output:</p>

<pre><code>    not ok 1 - The b key is false
    # Failed test &quot;The &#39;b&#39; key is false&quot;
    # at some_file.t line 10.
    # +------+------------------+-------+---------+
    # | PATH | GOT              | OP    | CHECK   |
    # +------+------------------+-------+---------+
    # | {b}  | &lt;DOES NOT EXIST&gt; | FALSE | FALSE() |
    # +------+------------------+-------+---------+</code></pre>

<p>In Perl, you can have behavior that is different for a missing key vs. a false key, so it was decided not to count a completely absent value as false. See the <code>DNE()</code> shortcut below for checking that a field is missing.</p>

<p>If you want to check for false and/or DNE use the <code>FDNE()</code> check.</p>

</dd>
<dt id="$check-=-D()"><a id="check---D"></a>$check = D()</dt>
<dd>

<p>This is to verify that the value in the <code>$got</code> structure is defined. Any value other than <code>undef</code> will pass.</p>

<p>This will pass:</p>

<pre><code>    is(&#39;foo&#39;, D(), &#39;foo is defined&#39;);</code></pre>

<p>This will fail:</p>

<pre><code>    is(undef, D(), &#39;foo is defined&#39;);</code></pre>

</dd>
<dt id="$check-=-U()"><a id="check---U"></a>$check = U()</dt>
<dd>

<p>This is to verify that the value in the <code>$got</code> structure is undefined.</p>

<p>This will pass:</p>

<pre><code>    is(undef, U(), &#39;not defined&#39;);</code></pre>

<p>This will fail:</p>

<pre><code>    is(&#39;foo&#39;, U(), &#39;not defined&#39;);</code></pre>

</dd>
<dt id="$check-=-DF()"><a id="check---DF"></a>$check = DF()</dt>
<dd>

<p>This is to verify that the value in the <code>$got</code> structure is defined but false. Any false value other than <code>undef</code> will pass.</p>

<p>This will pass:</p>

<pre><code>    is(0, DF(), &#39;foo is defined but false&#39;);</code></pre>

<p>These will fail:</p>

<pre><code>    is(undef, DF(), &#39;foo is defined but false&#39;);
    is(1, DF(), &#39;foo is defined but false&#39;);</code></pre>

</dd>
<dt id="$check-=-E()"><a id="check---E"></a>$check = E()</dt>
<dd>

<p>This can be used to check that a value exists. This is useful to check that an array has more values, or to check that a key exists in a hash, even if the value is undefined.</p>

<p>These pass:</p>

<pre><code>    is([&#39;a&#39;, &#39;b&#39;, undef], [&#39;a&#39;, &#39;b&#39;, E()], &quot;There is a third item in the array&quot;);
    is({a =&gt; 1, b =&gt; 2}, {a =&gt; 1, b =&gt; E()}, &quot;The &#39;b&#39; key exists in the hash&quot;);</code></pre>

<p>These will fail:</p>

<pre><code>    is([&#39;a&#39;, &#39;b&#39;], [&#39;a&#39;, &#39;b&#39;, E()], &quot;Third item exists&quot;);
    is({a =&gt; 1}, {a =&gt; 1, b =&gt; E()}, &quot;&#39;b&#39; key exists&quot;);</code></pre>

</dd>
<dt id="$check-=-DNE()"><a id="check---DNE"></a>$check = DNE()</dt>
<dd>

<p>This can be used to check that no value exists. This is useful to check the end bound of an array, or to check that a key does not exist in a hash.</p>

<p>These pass:</p>

<pre><code>    is([&#39;a&#39;, &#39;b&#39;], [&#39;a&#39;, &#39;b&#39;, DNE()], &quot;There is no third item in the array&quot;);
    is({a =&gt; 1}, {a =&gt; 1, b =&gt; DNE()}, &quot;The &#39;b&#39; key does not exist in the hash&quot;);</code></pre>

<p>These will fail:</p>

<pre><code>    is([&#39;a&#39;, &#39;b&#39;, &#39;c&#39;], [&#39;a&#39;, &#39;b&#39;, DNE()], &quot;No third item&quot;);
    is({a =&gt; 1, b =&gt; 2}, {a =&gt; 1, b =&gt; DNE()}, &quot;No &#39;b&#39; key&quot;);</code></pre>

</dd>
<dt id="$check-=-FDNE()"><a id="check---FDNE"></a>$check = FDNE()</dt>
<dd>

<p>This is a combination of <code>F()</code> and <code>DNE()</code>. This will pass for a false value, or a nonexistent value.</p>

</dd>
<dt id="$check-=-L()"><a id="check---L"></a>$check = L()</dt>
<dd>

<p>This is to verify that the value in the <code>$got</code> structure is defined and has length. Any value other than <code>undef</code> or the empty string will pass (including references).</p>

<p>These will pass:</p>

<pre><code>    is(&#39;foo&#39;, L(), &#39;value is defined and has length&#39;);
    is([],    L(), &#39;value is defined and has length&#39;);</code></pre>

<p>These will fail:</p>

<pre><code>    is(undef, L(), &#39;value is defined and has length&#39;);
    is(&#39;&#39;,    L(), &#39;value is defined and has length&#39;);</code></pre>

<h2 id="EVENT-BUILDERS"><a id="EVENT"></a>EVENT BUILDERS</h2>

<p><b>Note: None of these are exported by default. You need to request them.</b></p>

<p>Check that we got an event of a specified type:</p>

<pre><code>    my $check = event &#39;Ok&#39;;</code></pre>

<p>Check for details about the event:</p>

<pre><code>    my $check = event Ok =&gt; sub {
        # Check for a failure
        call pass =&gt; 0;

        # Effective pass after TODO/SKIP are accounted for.
        call effective_pass =&gt; 1;

        # Check the diagnostics
        call diag =&gt; [ match qr/Failed test foo/ ];

        # Check the file the event reports to
        prop file =&gt; &#39;foo.t&#39;;

        # Check the line number the event reports o
        prop line =&gt; &#39;42&#39;;

        # You can check the todo/skip values as well:
        prop skip =&gt; &#39;broken&#39;;
        prop todo =&gt; &#39;fixme&#39;;

        # Thread-id and process-id where event was generated
        prop tid =&gt; 123;
        prop pid =&gt; 123;
    };</code></pre>

<p>You can also provide a fully qualified event package with the &#39;+&#39; prefix:</p>

<pre><code>    my $check = event &#39;+My::Event&#39; =&gt; sub { ... }</code></pre>

<p>You can also provide a hashref instead of a sub to directly check hash values of the event:</p>

<pre><code>    my $check = event Ok =&gt; { pass =&gt; 1, ... };</code></pre>

<h3 id="USE-IN-OTHER-BUILDERS"><a id="USE"></a>USE IN OTHER BUILDERS</h3>

<p>You can use these all in other builders, simply use them in void context to have their value(s) appended to the build.</p>

<pre><code>    my $check = array {
        event Ok =&gt; { ... };
        event Note =&gt; { ... };

        fail_events Ok =&gt; { pass =&gt; 0 };

<dd>

</dd>
<dt id="$check-=-event-$TYPE-=&gt;-{-...-};"><a id="check---event--TYPE1"></a>$check = event $TYPE =&gt; { ... };</dt>
<dd>

<p>This works just like an object builder. In addition to supporting everything the object check supports, you also have to specify the event type, and many extra meta-properties are available.</p>

<p>Extra properties are:</p>

<dl>

<dt id="&#39;file&#39;"><a id="file"></a>&#39;file&#39;</dt>
<dd>

<p>File name to which the event reports (for use in diagnostics).</p>

</dd>
<dt id="&#39;line&#39;"><a id="line"></a>&#39;line&#39;</dt>
<dd>

<p>Line number to which the event reports (for use in diagnostics).</p>

</dd>
<dt id="&#39;package&#39;"><a id="package"></a>&#39;package&#39;</dt>
<dd>

<p>Package to which the event reports (for use in diagnostics).</p>

</dd>
<dt id="&#39;subname&#39;"><a id="subname"></a>&#39;subname&#39;</dt>
<dd>

<p>Sub that was called to generate the event (example: <code>ok()</code>).</p>

</dd>
<dt id="&#39;skip&#39;"><a id="skip"></a>&#39;skip&#39;</dt>
<dd>

<p>Set to the skip value if the result was generated by skipping tests.</p>

</dd>
<dt id="&#39;todo&#39;"><a id="todo"></a>&#39;todo&#39;</dt>
<dd>

<p>Set to the todo value if TODO was set when the event was generated.</p>

</dd>
<dt id="&#39;trace&#39;"><a id="trace"></a>&#39;trace&#39;</dt>
<dd>

<p>The <code>at file foo.t line 42</code> string that will be used in diagnostics.</p>

</dd>
<dt id="&#39;tid&#39;"><a id="tid"></a>&#39;tid&#39;</dt>
<dd>

<p>Thread ID in which the event was generated.</p>

</dd>
<dt id="&#39;pid&#39;"><a id="pid"></a>&#39;pid&#39;</dt>
<dd>

<p>Process ID in which the event was generated.</p>

</dd>
</dl>

<p><b>NOTE</b>: Event checks have an implicit <code>etc()</code> added. This means you need to use <code>end()</code> if you want to fail on unexpected hash keys or array indexes. This implicit <code>etc()</code> extends to all forms, including builder, hashref, and no argument.</p>

</dd>
<dt id="@checks-=-fail_events-$TYPE;"><a id="checks---fail_events--TYPE"></a>@checks = fail_events $TYPE;</dt>
<dd>

</dd>
<dt id="@checks-=-fail_events-$TYPE-=&gt;-sub-{-...-};"><a id="checks---fail_events--TYPE---sub"></a>@checks = fail_events $TYPE =&gt; sub { ... };</dt>
<dd>

</dd>
<dt id="@checks-=-fail_events-$TYPE-=&gt;-{-...-};"><a id="checks---fail_events--TYPE1"></a>@checks = fail_events $TYPE =&gt; { ... };</dt>
<dd>

<p>Just like <code>event()</code> documented above. The difference is that this produces two events, the one you specify, and a <code>Diag</code> after it. There are no extra checks in the Diag.</p>

<p>Use this to validate a simple failure where you do not want to be bothered with the default diagnostics. It only adds a single Diag check, so if your failure has custom diagnostics you will need to add checks for them.</p>
